And you, Jeff, like the majority of pretend sailors here, consistently
fail to remember Rule 1 which states "First she's a sailboat".

Any and all discussion of volume and or displacement of water which
boils down to mass can be more simply stated using LOA since
ballasted monohull sailboats all fall within a predictable range of mass.

When one keeps Rule 1 in mind at all times it becomes increasingly
evident that everything - yes, even motors (some absurd people
have TWO of them) come second, third, fourth etc. It follows that
since 'first she's a sailboat' that any and all motors are intended to be
a supplement and only needed for flat water when there is no wind.

Any and all other reasons to use your motor(s) that require such ridiculous
levels of HP and weight violate Rule 1. This cannot be argued.

S.Simon - keeps his priorities straight.

Sorry about the late reply - I'm just catching up ...

Your claim of "one horsepower for every foot of length" is absurd and shows a remarkable
lack of understanding of nautical science.

Required HP is not a function of length, it is a function of displacement. The Simplistic
way to remember this is that moving the boat requires pushing aside a volume of water
equal to the displacement. The rough rule of thumb is that one HP for each 500-600 pounds
of displacement is required to push a boat to hull speed.

For a Coronado 27, this works out to about 10-12 HP. For a Hinckley Bermuda 40, a boat
Bill Tripp would prefer to be remembered for, this is 40 HP. The newer H42 displaces
23,500 and has 50 HP; the 51 displaces 40,000 and has 88 HP. All perfectly appropriate.
Remember that diesel should be run at 80% rpm, where the output is considerably less than
the rated power.

So how does displacement vary with length? This is roughly a "cubic" function. The
"Displacement/Length" ratio is roughly constant for a given design style, and is usually
computed as "Tons / ( (WL ft/100) **3). Thus, a boat twice as long will displace 8 times
as much, and require 8 times the HP. This fits in with the boats listed.

Once again, Neal has displayed mathematical and scientific skills consistent with his
education as an English major.

Dear Ms. Carroll

You're beginning to catch on, Mam! Of course, any boat
that has more than one horsepower for every foot of length
in NOT a sailboat. It is simply a motor boat with spars.
The very best it can be called is a "motor sailer."

Think of how absurd the very idea of 50 horsepower in any
42-foot motor boat with masts really is? It only takes 20 horses
to drive that particular Hinckley to hull speed. So, why all the
extra power and weight? The answer is simple. It's because
the boat is designed to motor and charge huge battery banks
to run all manner of unnecessary crud that really has no business
aboard a sailboat. Nobody but rich, ignorant snobs own Hinckley's
anyway. Hinckleys are an example of a boat that is way way way
overpriced for what you get. Only rich ignorant snobs spend
so much money on a name. These same people wear Rolex
Oysters not because they keep any better time than a cheap
Timex but because they think it gives them status.

Well, the bottom line is their boat and wrist watch are only owned
so they can feel good about themselves. For the most part these
people are no different than Bobsprit except they have money to
burn. They think brand names mean everything and since they can
buy pretty much whatever they want they buy things they think
will make people the most envious. Little do they realize real
sailors laugh at them and their ignorance. Real sailors know what
these pathetic individuals are all about. We laugh when we see
them motoring their so-called sailboats around expecting folks
to ooh and aah!

Would that they were more honest and just bought a motor boat
in the first place.

S.Simon - has more common sense than most people

So a Hinkley Sou'wester is not a sailboat? 50 hp at 42 feet.

So, a 38' Cabo Rico is not a sailboat? BS.


A Cabo Rico 38' is, indeed, a motor boat with sails unless someone
had one commissioned without motor. Any sailboat that has a built in
motor with more than one horsepower for each meter of length is a
motorsailer at best.

What's a Cabo Rico 38 have? About 40-50 horsepower? To be
a sailboat it would have to have no more than 12 horsepower.
